Validation and extension of management strategies for wheat powdery mildew

The objectives include validation of the effectiveness of varietal resistance, application rates and timing, efficacy of pre and post emergent fungicides to assess how different actives (DMI, QoI and SDHI fungicides) perform in the presence of resistant powdery mildew mutations.In 2022 the project had three main field componentsInvestigating best management of wheat powdery mildew through small plot trials.Surveying grower paddocks to determine frequency of mutations conferring reduced sensitivity or resistance to DMI and QoI fungicides.Understanding the cause of spatial variability in mildew incidence related to soil type. Collecting samples from for nutrient analysis.
